美国SomaLogic 
SomaLogic的aptamer技术是基于核酸与特定蛋白质结合，使其具有高度的选择性和专一性。按照一定排列顺序装配后，该技术可同时在生物液体样品中测出数百甚至上千种蛋白质，其中的一些蛋白质可能与某些疾病相关。Aptamer序列与特定疾病蛋白质相关联的作用被认为将在疾病的诊断和治疗方面起到显著作用。

SomaLogic is developing next-generation medical diagnostics based on protein signatures—unique patterns that can be analyzed using simple blood tests and that can distinguish between disease and health with unprecedented accuracy.

Proteins are critical for the normal functioning of the human body. They provide structure, transmit and receive information, and carry out important chemical reactions. In persons with a disease, many proteins may be affected. Compared to normal health, some proteins may become overly abundant, while others may become scarce.

By measuring these proteins—or biomarkers—SomaLogic is discovering new insights into disease and health. By combining biomarkers into patterns or disease signatures, SomaLogic is bringing new levels of accuracy to virtually every aspect of patient care: disease screening, diagnosis, therapy selection, and patient monitoring.

SomaLogic uses its unique aptamer array technology and bioinformatics capabilities to discover disease-specific biomarkers and protein signatures. Using a simple blood test, clinicians will have the information to transform medical practice and make a real difference in people's lives. The approach can be applied across a broad spectrum of clinical challenges faced by physicians.

Proteins say a lot about a person, and SomaLogic is discovering what they say.
